I was so crampy in my first two months of pregnancy that I didn't even take a pregnancy test for several weeks becuase I kept thinking my period was going to start. Everything will probably be fine- make sure you are drinking plenty of water and getting plenty of calcium (a common culprit with pregnancy cramping). I would also recommend finding a care provider who better and more compassionately addresses your concerns. It sounds like she just dismissed you.
Congratulations.
